THREAD CLEANER. 2

Application filed October 28, 1327. Serial No. 229,391.

This invention relatesto a thread cleaner, and has for an object to provide an proved construction wherein an eflicient cleaning may be secured, and at the same time a proper sizing of the thread secured.

Another object of the invention is to pro vide a combined thread cleaner andsizer for silk threads, wherein the cleaner is made of a plurality of parts .with means for accurately spacingv certain parts, whereby a proper size aperture is presented through which the thread passes.

A further object of the invention is to provide a thread cleaner, wherein means are provided for indicating the size accurately, measuring the size, and permitting d1iferent size jaws to be used without detracting from the accuracyof the thread opening.

In the accompanying drawing- Figure 1 is a fragmentary sectional view through a threadcleaner shown in position.

Figure 2 is a fragmentary side View of the guide and associated partsshown Figure 1, certain parts being broken away.

Figure 3 is a side elevation of the guide shown in Figure 1.

Figure 4 1s a view similar to Figure 3, but showing a slightly modified form of the invention.

Figure 5 is a view similar to Figure 3, but showing the parts on an enlarged scale w th the lower portion in section for illustrating the arrangement of pins, screws and associated parts.

Fi ure 6 is a view similar to F gure 5 but showing a modified construction.

Figure 7 is a view similar to Figure 6 except that both blades are formed identical with the exception of the threaded portion.

Figure'S is a perspective view of the shim and legend block shown in Figure .3.

Figure 9 is a erspective new of a modified form of bloc to that shown in Figure 8.

Referrin to the accompanying drawing by numerals, 1' indicates a-guide rail of? a desired structure, and 2 a thread gulde sl 1dingly mounted on rail 1. 'The thread guide 2 is provided with a cleaner receiving opening or passageway 3 and cut-away portions 4 merging into the passage-way 3 and extending to the lower surface of the guide. A cleaner 5 is positioned in the passageway 3 and arranged so that the rod 6 will strike the shoulders 7 formed by the cutaway portions 4 while the lower end of the mounted on or formed in block 11 carrying the spacing blade 12. This blade or shim is made accurately of certain thickness, as for instance, tour thousandths of an inch.

Preferably the block 11 is constructed findependently of the shim 12. and the shim is welded or otherwise secured to the block,

though if desired, the block and shim could jltlCle in onepiece as shown in the modified form 1n Figure 4.

As shown clearly 1n Figures 5 and '8, the

shim 12 is provided with an aperture 12' through which the rod 6 extends, while the shnnand block are both provided with an aperture 13 for accommodating the screw 1 1 The rod 6 acts as means for lining up the parts and holding the shim and block in place until screw 14 has begun to function. This rod also acts to prevent the cleaner from accidentally moving out of the guide '2.

Preferably the rod 6 is held in one of the plates of the cleaner by friction and loosely extends to the other plate. The cleaner 5 is formed with cleaning blades 15 and 16 and a clamping set screw 14, and the block 11 with its spacing blade 12 The blades 15 and 16 are provided with straight edges or faces 17 and 18 which are parallel when the blades are assembled, and thereby make a true slot of the desired width for accommodating the thread being treated.

From Figure, 3 it will be noted that the blades are provided with notches 19 and 20 respectively, and with apertures for receiving the screw 14. It will be noted that the blade 15 is provided with a smooth aperture 21 and the blade 16 with a threaded aperture 22, whereby the blades can be clamped tightly against the shim 12 while the screw 14 passes through an aperture 23 in the block 11. This block has been shown round, but it could be, square or some other shape if desired. Also, this block is Preferably made appreciably smaller than ;form of the invention,-

the opening presentedby the notches 19 and 20 whereby a space is presented which acts as a clean-out hole, thus permitting an instrument to be inserted through the hole 24: in the guide .2 and into the space around the block 11 so that the loose strands of thread, dirt and foreign matter may be removed from time to time. By forming the blade 12 accurately, the clean-out slot 7 will be accurate and, consequently, the clean thread will be substantially accurate, which in turn results in a better grade of goods woven from the thread.

When either of the blades 15 or 16 wears,

it may be removed and sharpened by grinding or otherwise resurfacing the edges 17 and 18. After the edges 17 and 18 have been ground so as to be pertectly straight,

they may be again inserted and screw 14 tightened. It the blade or shim 11 is accurate, the slot 7 will also be accurate. This may be done a number of times orunt-il the respective blades 15 and 16 hare been worn down to a great extent.

In Figure (3, a modified form of the invention is shown which is similar to that shown in Figure 5, except that blade 15' is not provided with a notch, whereas the notch in blade 16' accommodates the entire block 26. This block is shown square, but it could be some other shape without departing from the spirit of the invention. A shim 27 is secured to block 26 by welding or in any other desired manner, and if desired, may be provided with apertures 28 and 29 so that either end of the shim will accommodate the rod 6. An aperture 30 extends through the center of the shim and through the block 26 for accommodating, the screw 14.

In the arrangement of blocks and shims shown in Figures 8 and 9, and also in the other figures, the shim has been illustrated as extending on each side of the block as this is a preferable structure, but if desired, the shim could extend only on one side of the block. Also, it will be understood that the shim does the spacing and could act without the block if the legend 10 was not desired.

In Figure 7.. a further modified form of cleaner is shown, wherein the blades 15" and 16 are identicalin construction.each being provided with a notch 31 so that either blade may receive the block 26. In this as well as the preferred form, the facing edges of the blades may be ground oil from time to time so that accurate work may be secured. It will be understood that. the facing edges ol the respective blades are ground from one end to the other, while the spacing blade or shim .27 is never grtmnd, as it originally made accurately and will always remain accurate as there is no wear thereon.

What I claim is:

1. A thread cleaner, comprising a pair of cleaning blades, one oi said blades harinc a l'lOi'"il therein near one end, a spacing blade arranged between said blades, a bloc]; secured to said. spacing blade and extending into said notch, and means for clamping said cleaning blades against. the spacing blade, said notch being of a sine to accommodate said block whereby the block will not be brought under tension.

2. It thread cleaner, comprising a pair of clcaniilg' blades, one of said blades having a notch, :1 spacing blade arranged between the first mentioned blades, :1 block secured to said spacing blade, said block being loosely littcd into said notch, means on the blot-l: indicating the thickness oi? said spacing blade, and means for elampi said cleaning blades against the spacing l; le.

3. A. thread cleaner,comprising a pair oi cleaning blades of substantially identical construction, each blade having a. notch near one end opening onto the operating edge of the blade. a spa blade arranged between the lirst mentioned blades, :1 block secured to said spacing blade fitting into one oi said notches, and means for clampingsaid clean ing blades against said spacing blade.

-l-. A thread cleaner. comprising a pair of cleaning blades. each blade having an accurately faced edge, a notch in the respective edges, an aperture near one end of each (i-leaning blade and an aperture merging into each notch, one of said cleaning bla lei being formed with threads in the second mentioned aperture, :1 pin ettending through the apertures near the ends of said blades, a spacing blade arranged between said blades and in engagement with said faced edges. and a clamping screw fitted into the apertures merging into said notches, said clamping screw extending through said spacing blade with the threaded end. of the screw engaging the threaded opening whereby the screw will clamp the blades against said spacing blade.
